What is the difference between data masking and anonymization?

What is the difference between data masking and anonymization?

Data masking involves altering data to protect sensitive information while keeping its format, whereas anonymization removes all identifiable information.

Can you give me examples of when to use each method?

Sure! Use data masking when you need to share data with third parties but want to protect sensitive details. Anonymization is best for datasets used in research where individual identification is not necessary.

Are there any legal implications for using one over the other?

Yes, data masking may still be subject to regulations like GDPR if the data can be re-identified, while anonymized data is generally considered outside of such regulations.

Which method is more secure?

Anonymization is generally considered more secure since it irreversibly removes identifiable information, while data masking can potentially be reversed.
